8 Claims.

This invention relates broadly to a friction device for filling carriersand particularly to a holder by means of which a friction device may beeffectively held in a position to yieldingly engage that filling carrierlocated in a rotary hopper for car- 1 riers which is located intransferring position and the end that the filling will not unwind fromthe carrier and be subjected to the danger of breaking during thesubsequent operation of the shuttle after the carrier has-beentransferred thereto.

Another object of the invention is to provide a holder of novelconstruction by which the friction member of the device may be guidedand adjusted together with a means for simultaneouslyclamping thefriction member to the holder and the holder to asupport. f

Another object of the invention is to embody in the device a frictionelement of a character which will yield upon engagement with the fillingto conform slightly to irregularities on the surface of the filling andwhich will not cause injury to the filling because of its engagementtherewith. Still another object of the invention is to so' construct thefriction devicethat it will also constitute an effective means foraiding and supporting a filling carrier while said carrier is located intransferring position. I

The invention consists in a friction device for filling carriers as setforth in the following specication and particularly as pointed out inthe claims thereof.

Referring to the drawing:-

In the drawing, referring to Figs. l-to 4 inclu-- 5 sive, 5 represents aportion of the frame of a filling replenishing loom, t a lay, l ashuttle boxand 8 a shuttle positioned in said box. Mounted. upon theframe 5 is a stand 9 for a rotary bobbin disc I!) constituting a portionof a hopper III in which 10 a plurality of bobbins I2 constitutingfilling carriers are mounted in a well-known manner. Mounted on thestand 9 is a fixed transferrer stud l3 upon which is pivo-tallymounted atransferrer to which a transferrer dog It is pivotally attached at H.The dog It is adapted to be engaged by a bunter l8 mounted on the lay 6to effect the operation of the transferrer I4 in a well-known manner andcause a bobbin l2 which is located in transferring position in thehopper ,II to be forced downwardly from said hopper into the shuttle 8.v i

All of the parts hereinbefore mentioned are old and their operation iswell known in the art. It is also well known that portions of thismechanism, particularly the hopper l l, are caused to vibrateexcessivelywith the result that therevis a tendency for the fillingcarriers l2 to rotate upon the portions of the hopper upon which th ey30 are mounted, thereby causing the filling to un- Wind. Whenthishappens it is a common 00- currence after the filling carrier hasbeen transferred to the shuttle for the filling thread to break when theshuttle is driven across the la'y'with 35 the result that the loom iscaused to stop and production therefore is stopped until the loom isagain started. j The friction device'of this invention is mounted uponan arm l9 which is rigidly fastened toflthe transferrer stud !3 by a setscrew 20. A finger 22 constituting a top holder is rigidly secured inany suitable manner to a pivot member 2| which is mounted to rotate inabearing provided at the Mounted upon the opposite end portion'of thepivot member 2| from that upon which the top holder 22 is mounted is afriction device 23 embodyingtherein a sleeve 24 which is secured to thepivot member 2| by a cotter pin 25 and said sleeve 24 therefore rotatesinunison with said pivot member. The sleeve 24 is recessed at 26 toprovide a space for receiving a coil spring 21 surrounding'the pivotmember 2! and one extremity of saidspring is connected to the arm l9 andthe other extremity to the sleeve 24 in a manner to cause the top holder22 to engage a stop provided upon the arm I I9 at which time the topholder will be located in a position to support the small end portion ofthe filling carrier l2 when said carrier is located in transferringposition.

Mounted upon and. extending around the peripheryof thesleeve' 24 of thefriction device 23 I is a holder 28 for a friction member 29. The

holder 28 is constructed as a band of sheet material and terminates atits opposite ends in parallel clamping portions 30 and-3l. The frictionmember 29 is adjustably mounted upon the clamping portion 3!! of theholder-2B-and is secured- I the holder havingparallel clamping portionsM and=45 embodied therein between which a fric- 15 thereto .by means ofa guide 33 and5bolt534, the

latter passing through the guide 33, through'a slot 35 provided in thefriction member 29 and through slots provided thereforin the'clampingportions 30 and 3| of the holder 28, and saidboltcharacteristics-of"rubber and is provided with a bevel surface 32 whichis adaptedto underlie the filling-carrier H which is located intransferring position-an'd yieldingly engages the filling thereon in amanner to prevent said carrier from r-otat- -"'ing inithe hopper ll.The'friction member 29 will furthermore actas an aid in supporting thecarrier l2 with which it contacts. It is desirable that the'materialofwhichthe friction member '29 is constructed shallbe suflicientlyflexible to conform slightly to the contour of the surface ofthefillingwith which said member contacts to "the-end that-said memberwill effectively grip the I filling .material 'andthereby prevent thecarrier fromrotating without injuring the filling.

' 'IhefrictionmemberZB is-adjustable toward and away from the fillingcarrier l2 with which 'it is adapted to contactin order that it may becorrectly positioned with respect to said filling carrier. .The frictionmember 29 is positioned upon' theholder :28 by'means of the guide 33which is constructed as an inverted U-shaped member, theparallel; armsof which engage the opposite edges of the clamping portion 30 of theholder, see Fig. 4, andwhen the friction member 50 "'29 is. clampedbetween the guide member 33 and 21 areall old'and'well known'in'the artand that the top holder 22 tips downwardly to release the carrier [2every, time -atransfer-is 'made. Applicant has utilizedthe pivot member2| and sleeve 1 24 as a support forhisimproved friction device'23.

In' the operation of 'the loom, as the hopper H is rotated tosuccessively position the filling car- I .Iriers l2 intotransferringposition, the'surface of the filling. of thecarrier next to betransferred I will engage the bevelled surface 32 of the friction thefriction device323 will rock in unison withthe top holder "22 as thelatter releases thecarrier.

' curely to a sleeve' 24 by means of a bolt 4| and nut 42. It is evidentthat the friction member '46 may be adjusted between the clamping por-10 tions 38 and 39 by moving said member 40 in-' wardly or outwardly asmay be desired.

- In Fig. '7 still another modified embodiment of the invention isillustrated in which 43 comprises tion member 46 is secured. The holder43 issecurely clamped to a sleeve 24 by means of a bolt 41' and nut 48.In securing this device to the sleeve to which it, is attached therewill be a 20 clamping action tocompress the friction member a betweenthe'portions 44 and 45, 'but'this action will not be as effectiveas inthe other embodimerits of the invention-previously described.
